Few books have dealt with the topic of exchanges in chess, leaving this important part of chess strategy a mystery to most. In Mastering Chess Exchanges, grandmasters Aagaard and Castellanos break down the topic into crystal-clear themes, including piece preferences, tension, weaknesses, colour complexes, king safety and endgames, illustrating the concepts with illuminating examples. Then the reader is given a chance to turn understanding into skill, with 365 instructive exercises, featuring a novel, multiple-choice format designed to focus attention on possible exchanges.
